Breakthrough laser technique holds quantum matter in stable packets
Physicists have, for the first time, created stable bright matter-wave solitons with attractive interactions inside a laser-generated grid. Unlike typical quantum waves that spread out, solitons remain concentrated in one spot. Using a Bose–Einstein condensate of cesium atoms cooled near absolute zero, the team trapped the atoms in an optical lattice of laser light and tuned magnetic fields to make them attract each other. This … Continue reading Breakthrough laser technique holds quantum matter in stable packets
